WINDOW ATTACHMENT.

Application filed December 23, 1919.

To all 'whom z' may concern:

Be it known that I, WALTER STnwARr BORLAND, of the city of Saskatoon, in the Province of Saskatchewan, Canada, have invented certain new and useful Improvements in Window Attachments, of which the following is the specication.

The invention relates to improvements in window attachments and particularly to an extension window structure and an object of the invention is to provide an extension window structure applied to a Vwindow frame and which will allow of clear uninterrupted vision both forwardly, rearwardly and laterally from the interior.

A further object of the invention is to construct the attachment so that it can be readily connected to existing window frames and removed therefrom when desired and further to arrange the attachment so that it can be collapsed when not in use.

A still further object is to provide an extension window frame particularly adapted for use on the cabs of locomotive windows whereby, when the attachment is installed, the engineer can see clearly both ahead and to the rear and without necessitating putting Yhis head out into the open air as at present occurs.

With the above more important and other minor objects in view,.which will become more apparent as the description proceeds, the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described ant4 later pointed out in the appended claims, reference being had to the accompanyingr drawings, in which Figure 1 is a side view showing my window attachment as applied on the cab of a locomotive engine.

Fig. 2 is a rear view.

In'the drawings like characters of reference lndicate corresponding parts in the several figures.

In the present disclosure I have show the extension frame as attached to the cab of a locomotive engine but I wish'it to be distinctly understood that I do not wish to be limited to this particular use of it as there are many other places where the said extension frame could be used to advantage. This feature will be readily appreciated and is not further enlarged upon.

Referring now to the drawings 1 represents the cab of a locomotive en;

gine having a window opening 2 therein, the opening being bounded Vby the window frame 3, this being actually formed aspart of the cab side.

Customarily the opening is closed by a sliding window sash 4: which slides ahead within the guides 5 and 6 to a position in advance of the opening as best shown in dotted outline in Fig. 1.

To the side of the cab I` attach my box like extension window 7, such extension win dow inclosing the opening 2 and providing head room for the engineer. The extension window is formed from a plurality of hinged sectionsarranged and constructed as now described.

The ends 8 and 9 of the extension frame are preferably formed from angle iron bent and cut to form open centered substantially rectangular end frames. To the bottom of the end 8 I connect pivotally as by hinges the extension frame. To the top of the end piece 9 I secure as by hinges 12 atop section 13, the free end of which overlies the upper end of the end piece 8. The sections 11 and 13 are preferably flat metallic plates Y and they are fitted at their outer edges with inturned stop flanges V14E and 15. The top section 18 is pivotally fastened by hinges 16 to the end member 8.

1n order to give rigidity to the structure it is Jfastened to the existing window frame which, in the present instance, is the window 'frame of the cab. A. releasable tastening is provided7 which fastening comprises ioY in the present instance four similar jack screws 1'?, 1S, 19 Y and 20. theV jaclf screwsV being carriedV in each instance by bearings 21Vand 22 provided on a carrying plate 23 which is secured to the adjacent end pieces. rlhe inner ends of the jack screws are fitted with pivoted levers 24 which can be swung up and down and whichprovide an easy ineans for operating the screws.

l/Vhen the extension `trarne is to be attached the jack screws are drawn in and the extension trame is fitted against the outer face of the window trame, the withdrawn jack screws at this time being contained within the frame as best shown in Fig. 2. Obviously by'tightening up the jack .screws Vagainst the topa-nd bottoni of the window traine the extension frame will be positively `clamped in position, the two end members 8 andi) then becomingstation'ary elements which hold the other parts of the structure in position. To prevent undesirable wear# ing of the window ramel Yhaveprovided metallic sockets'A to receive the" ends of the jaclrscrews. Y Y Y Here it will be observed that" the Vinner sidefof'the'extension 'frame opens through e the'interior'ot the window frame to the interior ofthe cab and that there is sufficient width in the'extension frame to allow the engineer to extend his head into-the eXtension frame through thewin'dow opening 2. In the outer corners of the extension frame I locate stationary vertically disposed Yc'orvner posts 25 and 26 and to the corner posts 'l secure end window sashesl 27 and 28 which arehinged to the 'posts' at 29 VsoV that they can be Vopened'when'desired for cleaning and otherfpurposes. These end sashes closey Ythe'openings -in the end frames 8 andf).V YTo the cornerposts l hinge also at 30 further window sashes 31 and 32 and these sashes carryother hinged sashes 33 and '34,

Y Vthe arrangement being such that when the sashes Vare opened or' extended theyL fully close the opening inthe outer side of the extension' frame asbest shown "in'FigL 9.

The hingesconnecting vthe latter sashes togetherand to thel posts are arranged so that the said sashes can Ybe foldedV in against the sashes 27and 28 as shown in Fig. 10 and in'such-'folded position .they are entirely conta-finedwithinV the ends 8 and 9.

vup into a'cornpact toriaY once it is released tom sections when in use.

from the trame by undoing the jack screws. ln folding, thesashesl, 529 33 and 34 are first folded into the end trames. Then the end sect-ion 8 is swung up to lie on top of the Ytop section 13. Then the bottom section 11 is folded in against the end section 8 and the end section 9 is closed in against the underside of the top section. ln this collaosed or stacked position the extension window appears as shown in Fig. 11. llhen it is stacked it is very convenient to carry about, such as when it is to be changed trom one cab'to another.

The flanges 14 and 15 form a stop for the sashes 81, 32, '33 and 34 when they are opened out as shown best in Figs. 7 and 9. ln Fig. 15 I have shown a modification of this device which, while still being collapsible, is attached by hinges to the side of the cab. lnl this structure the toi and bottom sections 35 and 36 and the end window sections 3? and 38 are hinged directly to the cab side and are arranged so that the end sections will pass between the top and bot The front window section 39 is then closed in against the end sections and between the top and bot- Vtorn sections and is held fast by spring clips 10.

FromV the above description it 'will be apparent that when this device is applied to a window frame one can see clearly either ahead, behind or outwardly without any Vdifliculty and such a vdevice lends itself par- 'ticularly to use on locomotivecabs where, under present conditions, an engineer hasto put his head out of the cab window to see ahead and back and under weather'conditions which are very adverse and particw larrly when traveling at comparatively high rate of speed. ltwill be seen also that the sash sections are all arranged so that they can be readily swung inwardly Vfor cleaningV or Ventilating purposes,V as occasion may demand. y A Y What l clai'in as my invention is Y 1. The combinatioirwith awindowV frame, vor" a bon like window attachment having the Yinner sideopen and the outer side and ends fitted with window sashes and jack screws carriedby the inner sideA of the extension window and engageable 4with the top and bottom olf the window frame and Vdetachably securing theextension window to the window frame. Y v' Y 2.
